Ialso just did a similiar test under NT 4.0, and the system took _aneternity_ to shut down (about 5 min, or so).

Use ZServer/Zope if you want supportedstuff), provided you can't find it and the Digital Creations folks don'tmind.> And, btw, does anybody have code that lets me create trees other than> binary?I.e., where a node has more than two children nodes. Lisp does it withcons cells, so it should be doable in Python, too.
